Hey all,

I’m a software dev working in an RF-heavy environment, and I built a bunch of calculators and some tools for myself.

I’m validating an impedance matching tool and would appreciate a sanity check.

Example case:

-Source: 50Ω

-Load: 25Ω

-Band: ~869–960 MHz

-Target RL: -10 dB

The tool suggests an L-match:

-shunt capacitor: ~3.6 pF

-series inductor: ~4.3 nH

Simulated S11 shows a nice dip (~-35 dB) around ~900 MHz and stays around -10 dB-ish across the band.

I’m not fully confident about:

1)whether an L-match is realistic over that bandwidth?

2)if the Q implied here makes sense?

3)how much parasitics would mess this up at ~900 MHz?

Does this look reasonable, or am I missing something?
